A 50-year-old man was admitted in our institution for non–ST-segment elevation acute coronary syndrome with troponin elevation. The patient had no prior heart disease and no cardiovascular risk factor. His medical history included ankle liposarcoma 4 years previous. He underwent post-operative radiotherapy and chemotherapy, and his disease was thought to be in remission. The routine echocardiography showed a voluminous intrapericardial and cardiac mass (Online Video 1). Extrinsic compression of the left coronary system was suspected, and accordingly, a computed tomography scan and a coronary angiography were performed. A large pericardial mass infiltrating the left ventricular wall was identified with compression of the left coronary system with subocclusions of the proximal left anterior descending (LAD) and left circumflex (LCX) coronary arteries (A and B, Online Video 2). Surgical biopsies were performed, and histopathologic examination revealed a myxoid liposarcoma (C). After repeated episodes of angina with diffuse ST-segment changes and because of its inoperability and poor radiochemosensitivity, a palliative percutaneous coronary intervention was decided upon. The percutaneous coronary intervention was performed with treatment of LAD and LCX subocclusions by implantation of 2 bare-metal stents with good angiographic results (D, Online Videos 3 and 4). The patient remained symptom-free and was transferred 3 days later to the oncology unit for chemotherapy. At 3-month follow-up, the patient was alive and free of angina. LM = left main.
